Abstract
A review of experimental evidence from the literature in relation to “impact fatigue”, “multiple impacts”, and “repeated impacts” on FRP composites, along with articles discussing theoretical and numerical simulations, is provided. A new terminology and definition is presented to clear the meanings of these types of loadings. Experimental investigations about the impact fatigue, have been categorized in terms of the impact energy and the number of impacts. Also, many parameters are considered to illuminate their effects during the repeated impacts on FRP laminates. Discussion of the reported results will be presented along with a recommendation for future explorations and research paths to fill in the knowledge gaps.
